Upper bound limit analysis of coral reef limestone cavern roof stability incorporating a tension‐shear failure mechanism with tensile‐strength cut‐off

Deep Underground Science and Engineering, EarlyView.
For the roof of coral reef limestone caverns, a novel tension‐shear composite failure mechanism was developed. The most critical tensile crack model was identified using a hybrid optimization algorithm, and the stability of the cavern roof was analyzed accordingly.

Health and Economic Impacts of an Early Labor Induction Policy for High‐BMI Mothers

Health Economics, EarlyView.
ABSTRACT We expand the literature on marginal returns to birth interventions by studying a common intervention: early induction of labor for a growing share of pregnancies, high‐Body Mass Index (BMI) women. We exploit Danish guidelines which recommend routine induction at 7 days after the expected due date instead of 10–13 days after for mothers with a

Political Transition, Health System Reform and Trust in Childhood Vaccination in Ukraine: A Qualitative Case Study

The International Journal of Health Planning and Management, EarlyView.
ABSTRACT Trust in childhood vaccination is a concern for health policy, particularly in settings of political transition and conflict, where governance, institutional legitimacy and service delivery are often under strain. It is against this backdrop that this study aims to describe evolving interactions between health system governance, trust and ...

First‐Trimester Crown‐Rump Length and Large for Gestational Age Newborns: What Correlation?

Journal of Clinical Ultrasound, EarlyView.
Our research found for the first time that uneventful pregnancies with LGA neonates are characterized by larger than expected CRL at the first trimester. CRL is one of the new markers that can be used to early identify fetuses at risk of increased fetal growth.
